Analyze Links On A Web Site

<## at this point in the active document, the base url is derived for anchor reconstruction ##> <## make the callurl the default baseurl until we find out otherwise ##> <## get ending position in string ##> <## now step thru string, from end to beginning looking for a slash ##> <## if the char at postion is not a slash, then we know that we do not have double slashes (if we had double slashs then we know that we moved *back* too far in the URL and there is no /filename found) ##> <## this is where the active document starts getting the links ##> <## flag to signal that we are inside an tag ##> Analysis Of Links On: &[callurl] <## the CALL tag loops through the objects returned by the remote web site and automatically creates variables which contain the different components of the object. An object is either a Tag or the Text in between Tags. ##> <## if we have an anchor tag ##> <## attribute counter ##> <## put the tag back together with HREF only ##> <## looking for HREF attributes ##> <## got one! ##> &[callvalue] <&[callobjectelement] <## According to spec, when the value in an attribute/value pair contains a number it should *not* be in double quotes, but when it has non-numeric information, it *should* be in double quotes. Since the CALL tag strips away double quotes from the value in attribute/value pairs, we need to determine if a value is non-numeric so that we can put the double quotes back on when we reconstruct the tag. ##> = >

<## relative link or mailto because no http in HREF ##> <## the following IF checks the object and makes sure that it has a / (slash) char at the beginning and adds it to the output object as long as it is not a mailto ##> <## now we add the relative link to the object or if it is a mailto then we assign the mailto value to the object ##> &[holdobject]
